PUMA Fabry-Perot Óptico
The PUMA interferometer is used in the Cassegrain focus of the 2.1m telescope in its configuration f/7.5. It consists of a focal reducer (collimator and camera lens) and designed to allow integration by a positioner in the collimated beam of various dispersive optical elements (interferometer, prisms, microlenses arrays, etc.). Currently it operates with a scanning Fabry-Perot interferometer (IFPB) ET-50 Queensgate and its parallelism device.
